technically the idle control on your vehicle is computer controlled and non adjustable. If the idle is high or low there is likely a code in your emission system (check engine light) and a sensor or emissions part that is not working properly or the computer itself. However if you look on throttle body you will find a slotted screw that will adjust the air/fuel mixture to get a better idle. When you find the screw be sure to have the engine running while you adjust it so you can hear the differences. If you would like to fix it properly you will need to the pull the codes from the computer diagnostic terminal. If you'd like to do that after adjustment of your air/fuel mixture post back. It would be a good idea to make a mark between the screw and the throttle body so that when you fix the emission related component causing the erratic idle you can put the screw back to its original position before restarting the engine

I'm not sure what category this would be under. I have a 1990 Subaru Legacy Wagon and if it sits for too long while the engine is running it heats up like crazy starts smoking and I am wondering if is going to make it another day. any suggestions please?I'm not sure what category this would be under.

very open question but its usually the idol control sensor. its attached to a cable usually open in the engine compartment. pulling this cable which goes back into the firewall will rev the engine. once you find the cable, find the bolt that attaches to the cable and tighten the cable, this will ajust at what RPM the car idols at and keep it from stalling when you let off the gas.
